Abstract (en)
A treatment device (2, 100) for performing a light-based treatment operation on or to a subject, the treatment device (2, 100) comprising: a light source (12, 101) configured to generate a light pulse, the light source (12, 101) comprising a gas; a plasma ignition unit (108) configured to apply a first voltage between the light source (12, 101) and a first electrode (102) to initiate plasma breakdown of the gas in the light source (12, 101); and a second electrode (106) connected to electrical ground; wherein the second electrode (106) is spaced from the first electrode (102) such that the first electrode (102) discharges via the second electrode (106) when the first voltage is applied.
